2018 Chevrolet Colorado ZR2: A Midsize Truck Built to Take on Tough Trails

The 2018 Colorado ZR2 combined midsize dimensions with DSSV dampers, front and rear lockers, extra clearance and trail protection. Here’s what Chevrolet’s figures show—and what they don’t.

The 2018 Chevrolet Colorado ZR2 paired a midsize pickup’s footprint with serious factory trail hardware: specialized Multimatic DSSV dampers, front and rear electronic locking differentials, extra ground clearance, and underbody protection. That equipment helps explain why Chevrolet pitched it as an unusually capable trail truck—but the available figures do not prove it performs like a full-size truck in a controlled comparison.

What makes the Colorado ZR2 different from a regular Colorado?

The ZR2 was a factory-built off-road version of the second-generation Colorado, not simply a standard truck with tires and accessories added. Chevrolet’s 2018 Colorado ZR2 Chevy Truck Playbook says its track was four inches wider and its ground clearance two inches higher than the base Colorado.

Chevrolet also fitted revised bumpers, rocker protection, skid plates, and electronic locking differentials at both axles. Locking the front and rear differentials can help maintain traction when a wheel loses grip on uneven terrain. The playbook contrasted this arrangement with the rear-only locker in the Tacoma TRD Pro comparison it cited; that is Chevrolet’s period manufacturer comparison, not an independent ranking of the trucks.

How do the ZR2’s Multimatic DSSV shocks work?

The signature suspension feature was Multimatic’s Dynamic Suspensions Spool Valve (DSSV) dampers. Rather than use one damping setup for every situation, their position-sensitive design was intended to combine composed everyday behavior with extra control during extreme off-road suspension compression.

  • CUSTOM FITMENT | Fits 2015 - 2022 Chevrolet Colorado; 2017 - 2022 Chevrolet Colorado ZR2 Model
  • THE BEST-SELLING, LOWEST-PROFILE HOOD SHIELD. | Aeroskin delivers aerodynamic, direct-mounted hood protection backed by the brand that invented the category.

  • DURAGARD. BUILT TO LAST. | Designed to stand strong against cracking and chipping, our DuraGard polymer guards your hood from dents, cleans easily, and resists scratches and fading.

In a November 16, 2016 launch release describing the 2017 Colorado ZR2, Multimatic explained the damper layout: two spool valves in each damper handle everyday compression and rebound damping, while a third, piston-mounted spool valve adds compression damping under extreme off-road use. The 2016 release concerns the 2017 launch model; the power and capacity figures below come from Chevrolet’s 2018 materials.

Multimatic says development testing and tuning began at GM’s Milford Proving Ground before moving to California’s Mojave Desert and GM’s Arizona Desert Proving Ground. That describes the development program, not an independent comparison test. At launch, Chevrolet executive Mark Reuss described the intended versatility this way: “You can go rock crawling on Saturday, desert running on Sunday, and comfortably drive to work on Monday.”

Can a midsize Colorado ZR2 handle trails like a full-size truck?

The ZR2’s equipment makes the comparison understandable: it had a wider track, increased ground clearance, front and rear lockers, and purpose-designed dampers, while remaining a midsize pickup. Those are meaningful trail-oriented differences from a base Colorado. They do not establish that it matches a full-size truck’s off-road performance; the manufacturer sources cited here provide no controlled full-size-versus-midsize test.

Its trail setup also came with a practical choice for spare-tire placement. Chevrolet’s 2018 Colorado catalog lists an optional bed-mounted full-size spare carrier intended to provide more rear clearance on steep terrain. Confirm model year, cab and bed fitment, and availability before buying one.
